error in running optimx

Hello,

The error message is quite clear, you must also install package 'quadprog'.
The 'quadprog' pkg is not listed as a dependency or even as 'suggested' and there is no mention of 'quadprog' in the NEWS file, nor does a search of the 'demos' code for a call to load "quadprog" produce a hit, and there is no mention of quadprog in the NAMESPACE file,  so the message while "clear" can still be considered "quite unexpected".
The "BB" package is imported by "optimx" and "BB" in turn imports "quadprog.

Hope this helps,

Hello,I tried installing optimx and got a confirmation that it was installed. However, anytime I call for it, I received the following error message
library("optimx", lib.loc="~/R/win-library/3.1")Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :   there is no package called ?quadprog?In addition: Warning message:package ?optimx? was built under R version 3.1.3 Error: package or namespace load failed for ?optimx?
When I go ahead to run my code, I have the following error message:
Error: could not find function "optimx"

How do I go about solving this issue.
Thanks.Olufemi
